Creating a Concatenated Volume
The V-Switch
supports a maximum
of 512 volumes.
To accommodate large volumes of data or to best utilize small volumes
spread over several disks, you can concatenate physical volumes across
storage devices to create a larger virtual volume.
In Figure 6-9, the volume is divided into two equitable chunks to be
mapped across two disks. Data blocks 1 – 4 are mapped to Disk 1, blocks
13 – 16. Data blocks 5 – 8 are mapped to Disk 2, blocks 13 – 16.
